HAY-PRESS.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed May 7, 1906. Serial No. 315,559.

To all whom it may concern:

Be it known that I, EUGENE W. KELSEY, a citizen of the United States,and a resident of Collierville, in the county of Shelby and State ofTennessee, have invented a new and Improved Hay-Press, of which thefollowing is a full, clear, and exact description.

The purpose of the invention is to improve upon the construction of haypress for which Letters Patent were granted to me July 3, 1906, No.825,132, which improvements consist in providing simplified and moredirect acting means for operating the plunger shaft from a cam orprojection extending downward from the under side of a main cam, saidprojection being in such a position as to act upon the short arm of alever, the long arm of said lever being attached to a plunger shaft, sothat as soon as the plunger shaft is released from the main cam the saidplunger returns to its normal or outer position after having completedits initial or rearward stroke.

Another improvement consists in the manner in which the tension springsat the rear of the bale-receiving compartment are applied, and inproviding the balin chamber with an automatically operated feeder andfolder, which latter revents the hay from returning into the balingchamber after it has been forced in the form of a bale into the rear orreceiving compartment of the press.

A further improvement consists in providing an apron carried by aplunger which closes the baling compartment or chamber while the plungeris at the inner end of its stroke, receiving hay which is fed to thebaling chamber until the above-mentioned lever returns the plunger toits normal or outward position, the feeder then forcing the hay into thechamber.

Another improvement consists in providing a hopper for the balingchamber, which can be employed to feed material thereto from either sideof the said chamber.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a lan View of the improved press Fig. 2 is a ongitudi'nalvertical section through the body portion of the press drawn upon anenlarged scale; Fig. 3 is a side elevation of the outer end of theplunger shaft, an edge View of the cam or lever acting thereon, andparts connected with the plunger shaft and the cam or lever. Fig.4 is abottom plan view of the cam or lever; Fig. 5 is a detai perspective viewof the end of the plunger shaft and cross head; Fig. 6 is a detail endview of the cross head; and Fig. 7 is a bottom plan view of the same.

A represents the body of the press. In the construction of this body abottom 10 is employed and a top 11 that extends to the back but stopsshort at the front, and its forward end 11 is given a rearward ordownward bevel or inclination as is clearly shown in Fig. 2, so that thefront portion of the body is open at the top. Side pieces 12 are securedto the top and bottom at the front open portion of said body, formingthereby a baling chamber B, open at the front as well as at the top; andthe said side pieces 12 extend rearward beyond the forward end of thetop 11 as is clearly shown in Figs. 1 and 2.

Flanged side pieces 12 extend down from the top 11 at the rear of theside pieces 12, and correspondingly flanged side pieces 12 extend upfrom the side portions of the bottom 10 as is shown in Fig. 2; otherwisethe rear portion of the body is open, and said rear portion back of thebaling chamber B constitutes a bale-receiving chamber B, being left openfor the purpose of applying the bale ties. The body is braced andstrengthened by cross pieces 14 located at the top, one at the rear endand the other at the inner end 1 1 of the top section, and correspondingsills 1 5 are located transversely of the bottom 10 of the body of thepress. The cross bars 14 and sills 15 are connected by side rods 15 inany suitable or approved manner. The forward end of the body, which isthe receiving end of the baling chamber B, is likewise strengthened by asill 15 bolted to the bottom 10, or otherwise securely fastened thereto.The body A of the press is usually further strengthened between thebaling chamber and its rear or delivery end by side beams 16, whichextend beyond the top and bottom sections 11 and 10, being connected byrods 17, which pass one rod over the top section 1 1 and the other rodbelow the lower or bottom section 10 as is illustrated in Figs. 1 and 2.

A series of apertures 18 is made in the sides 12 of the baling chamber Badjacent to the rear open portion of said chamber as is shown in Fig. 2and as is indicated by dotted lines in the same figure, keeper springs19 are secured at one of their ends to the outside of the side pieces 12adjacent to each slot or aperture 18, the heads of which springs aremade to extend into the baling chamber through the slots 18 in thecustomary manner, but prevent the material in the baling chamber fromworking backward after it has been forced into the receiving chamber B,assisted in such action by a folder to be hereinafter described.

The folder for the press consists of two metal leaves 20 and 21. Theleaf 20 is secured firmly to the inclined forward edge 11 of the uppersection 11 of the press, and extends down a slight distance into thebaling chamber B. The other leaf 21 is located in front of the fixedleaf 20, and at times is adapted to be carried rearward to an engagementwith said fixed leaf. The leaf 21 is secured to a shaft 22 mounted insuitable bearings at the upper rear portion of the baling chamber B, asshown in Fig. 2, and a crank arm 23 is provided at each end of the shaft22 outside of the baling chamber B. A weight 24 is adjustably secured toeach crank arm 23 by means of a set screw 25 or its equivalent. Theseweighted crank arms 23 serve to normally hold the leaf 21 separated fromthe fixed leaf 20 and in a vertical position within the baling chamberas is shown in Fig. 2.

When the plunger C, which has sliding movement in the baling chamber Bis carried rearward to force the contents of the baling chamber into thereceiving chamber B, the said plunger forces the hinged and weightedleaf 21 of the folder up against the fixed leaf 20, permitting theplunger to force the material from the baling chamber; but as theplunger C returns the weighted leaf 21 automatically drops to itsvertical position, preventing the return of material into the saidbaling chamber.

The rear end portion of an apron 26 is lo cated upon the top of theplunger C, being attached thereto about centrally between its sides by aivot pin 27, in order that the said apron 26 s all not bind in thebaling chamber B as the plunger is moved backward and forward. Thisapron closes the top of the baling chamber when the plunger C is at therear end portion of said chamber, and should any material be fed at suchtime to the baling chamber it will be received upon the apron, fromwhence it can be readily removed as the plunger C is on its returnstroke.

In connection with the baling chamber B I employ a feeding device. Thisfeeding device consists of op osing angular castings 28, whicharemounted to turn at the junction of their'members uon a shaft 29extending ac i said shaft being rovided with suitable nuts 30 at itsouter em s. An arm 31 is secured to the upper member of each casting 28,and the said arms 31 are in parallelism with the parts of the casing toWhich they are secured. At the rear end of each arm 31 an enlargement orhead 32 is provided, which occupies a position more or less at an angleto the arms 31 as is shown in Fig. 2 and rods 33 are made to connect theheads 32, the said rods and heads being adapted as the plunger iscarried out- Ward from the baling chamber, to be dropped downward andpress the loose material into the baling chamber, which action is accomlished by attaching other sections 34 to the lower or vertical membersof the castings 28, and in these lower members 34 slots 35 are produced,which slots loosely receive pins 36, extending from the sides of theplungerC; and when the plunger C is at its innermost position the upperor pressing portion of the said plunger will have the upper inclinedposition out from the baling chamber as is shown by dotted lines in Fig.2.

Forward extensions 34 in the form of side sills are provided for thelower front portions of the sides 12 of the baling chamber B. Theseextension sills 34* are each attached to a beam 36. These beams extendin parallelism forwardly from the baling chamber as far as may berequired, resting upon a transverse sill 37. A pivot 39 is made integralwith the base 38 aboutmidway between its sides as is shown in Fig. 1,and concentric curved guide rails 40 and 41 are curved around the 0st 39at one side thereof and are remover a required distance therefrom, andthese guide rails are supported at an elevation above the beams 36 or inany suitable manner by underlying cross bars or lates 42.

A shaft C is secure at its inner end in any approved manner to the pluner C, and this plunger shaft C is sufficiently ong to extend over theguide rails 40 and 41. An upper strap 43 .is secured to the outer orforward end of the plunger shaft C, and a strap 44 is secured to theunder face of the said plunger shaft, and this strap has a cross head 46formed on its under side as shown in Fig. 5, the lower portion whereofpasses between the guide rails 40 and 41, being circular in order torevent binding; and between the outer cm s of said straps a roller 45 ismounted to loosely turn. The cross head 46 serves to guide the forwardor outer end of the plunger shaft as the plunger moves forward andbackward in the baling chamber B.

Under the form of construction shown in Figs. 1 and 3, a link 47 ispivoted to the under face of the plunger shaft 0 at for example itsright-hand side, the link 47 extending forward and outward beyond saidside, as clearly illustrated in Fig. 1; and the forward end of the link47 is pivotally attached a to a leyer arm 48 which extends beneath theplunger shaft C to the opposite side of the guide rails 40 and 41, andits unattached end is more or less forwardly curved and is fulcrumed bya suitable pin 49 preferably upon the inner or rear end portion of theconnected guide rails as is shown in Fig. 1. Forward of the pivotalportion of the said lever arm 48 a roller 50 is mounted to revolve,extending upward from the lever arm as best shown in Fig. 3.

In connection with the plunger shaft C an operating lever or cam D isemployed. This cam or operating lever is mounted at its central portionto turn loosely around the pivot 39, and the said cam or operating leverD is provided at its ends with cam surfaces designated respectively 50and 51, which cam surfaces are more or less semi-elliptical and face inopposite directions, and when the lever arm 48 is employed for thepurpose of returning the plunger shaft C to its outer or normalposition, cams 52 are rojected downward from opposite diagonal cornersof the said operating lever D, as shown particularly in Fig. 4, the saidlu s being near the ends of the cam and a litt e forward of the extremeend of the cam with relation to its movement.

Draft arms 53 are secured to the operating lever D at opposite sides ofits center, adapted to carry a swingletree for example at its outerends, and a diagonal hitching bar 54 is secured to the draft arms 53 andextend beyond that side of the arm at which the draft device orswingletree is located, the hitching arm being adapted for the customarypurpose of connecting the forward portion of the harness of the draftanimal thereto.

In the operation of this form of the device, as the operating lever D isrevolved and a cam surface 50 or 51 is brought in contact with theroller at the outer end of the plunger shaft C, the said shaft is forcedrearward, and consequently the plunger 0 is made to travel on its rearor compressing stroke in the baling chamber. As soon as the cam surfacesor 51 has forced the plunger C as far rearward as necessary anddisengages from the roller 45 on the plunger shaft C, a cam 52 adjacentto the particular cam surface engaged, will be brought into engagementwith the roller 50 on the lever arm 48 and will force its roller bearingend rearward, thus carrying its opposite end forward and causing theplunger shaft C and its attached plunger 0 to be drawn out the limit ofthe return stroke.

At the rear of the upper opening of the baling chamber B, a guard railor block 68 is secured upon the cross beam or bar 14, as is shown inFig. 2, and this guard block 68 is provided with a strap 69 on its upperface, which strap extends down along each end of said block yet isspaced from said ends, and the guard block or rail 68 is made removableby attaching brackets 70 thereto and passing the said brackets throughloops 71 secured upon the upper face of the said cross bar 14, as isshown in Figs. 1 and 2.

A single side guard rail 72 is employed, which may be placed in positionat either side of the baling chamber; and one end of the side rail 72,when said rail is in position, is made to enter the space between theprojecting end of the strap 69 and the opposing end surface of the rearrail 68. The side rail 72 is provided with vertical brackets 73, whichextend beyond its lower edge, and when the side rail 72 is in positionenter keepers 74 secured to both outer side faces of the baling chamberB and at the open side of the baling chamber, or that which isunprotected by the guard rail 72 a feed trough 75 is located, havinglugs 76 extending downward therefrom and corresponding to the brackets73 of the guard rail 72, and the lugs of the feed trough are passed downinto the keepers 74 at the side of the baling chamber B adjacent towhich the feed trough is placed.

Braces 35 are carried from the extensions 34 of the baling chamber B upto the shaft 29 at the upper forward end of said chamber, as is shown inFig. 1. The rear end of the receiving chamber B is tensioncontrolled,and the rods 15 connecting the lower rear sill 1-5 with the upper crossbar 14 are secured to the cross bar but do not extend into the sill,since at each end of the sill parallel upright rods 77 are secured,connected at top by a plate 78. The rods 15 extend loosely through theplates 78 and are provided with heads 79 at their lower ends, andsprings 80 are coiled around the said rods between their heads 77 andthe guide plate 78, which springs have a tendency to draw the rear endportion of the upper section 11 of the baling press downward so as toexert more or less downward pressure on the finished bale as it leavesthe press.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1. In a hay press, a baling chamber, a plunger for thesame, a shaft secured to said plunger, a roller at the end of the shaft,fixed parallel and substantially elliptical guide rails, a cross head,at the roller end of the shaft having a cylindrical central portionadapted to operate between said elliptical guide rails, an operatinglever fulcrumed at its center adjacent the said guide rails, the saidrails being eccentric to the pivot of said lever, which lever isprovided with oppositely facing semi-elliptical end cam surfaces thatalternately engage with the shaft roller, and auxiliary cam extensionsfrom the under face of the operating lever adjacent its end camsurfaces, a return lever fulcrumed adjacent an inner end of said guiderails, a link connection between the return lever and said shaft,

and a roller at the pivoted end of the return lever for engagement withthe said auxiliary cams of the operating lever, the said operating leverin its rotation acting first upon the plunger shaft to force the plungerinward in the baling chamber, and next upon the return lever to returnthe plunger to the mouth of the said baling chamber.

2. In a hay press, the combination with the upper rear wall of thebaling chamber and a leaf fixed to said wall at the mouth of the saidchamber, which leaf has a downward and rearward inclination extending atits lower end within said chamber, of a shaft pivoted in front of thefixed leaf, a second leaf secured to said shaft, which leaf extendswithin the path of the plunger of the press, a crank arm located at anend of the shaft outside of the baling chamber, and a weight adjustablymounted upon said shaft.

3. In combination with the body, its baling chamber, and a plunger heldto slide in the baling chamber, of L-shaped arms, pivot ed at thejunction of their members at the sides of the baling chamber adjacentits forward end, each arm comprising a short member extending downwardwithin said chamber, and a longer member extending over the chamber, thelonger member of the arms hav ing their rear ends enlarged to extendabove and below the upper and lower edges of the main portions of saidmembers, the said e11- largements being given a downward and forwardinclination at their rear edges, rods fixed one above the other in theenlargements of the arms and pins extending from the plunger into slotsproduced in the shorter members of said arms.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
